Substitute Part Grouping Explanation

Substitution of the FX11LA-140P-SV(21) is determined by strict equivalence across the following critical parameters:

• Connector Type & Series: Header with outer shroud contacts, FX11 series
• Electrical Configuration: 140 positions, 2 rows, 0.020" (0.50mm) pitch
• Physical Dimensions: 2mm mated stacking height, 0.075" (1.90mm) height above board
• Contact Properties: Gold finish at 4.00µin (0.100µm) thickness
• Mounting Technology: Surface mount with board guide and solder retention
• Compliance: RoHS compliant, MSL 1 rating

Parts meeting all these parameters are classified as parametric equivalents and may be used interchangeably in applications requiring the FX11LA-140P-SV(21).

Parameter Comparison

Engineering Selection Recommendations
